Passport denial is a federal child support enforcement remedy that can prevent the issuance of a passport or revoke an existing one when a person has qualifying child support arrears. The threshold for federal passport denial is currently $2,500 in past-due child support.

Passport denial is administered through the federal government's Passport Denial Program which is connected to the state child support enforcement system.

For delinquent obligors who travel internationally or who need a passport for work passport denial is a significant leverage point for payment. Bringing arrears current is required to have the denial lifted.
